About this Mod

Adds a bunch of GD Lobotomy things, and more.
This project is also available on CurseForge!

This mod adds new blocks like the Normal difficulty block, Hard difficulty block, Extreme demon difficulty block and others, but not all demons.

This mod also adds 2 new cool tools! "Mr. 555 Sword" it deals a lot of damage. AND 555's pickaxe, which mines very fast.

This mod also adds new 2 blocks "Does He Know?" and "Mr. 555 Block" (hardest to mine).

More things like food or bosses will be added in future updates!
